Why Trim Lines?
Extra spaces at the start or end of lines are common when copying text from PDFs, Word documents, or web pages. These invisible characters can cause problems in Excel spreadsheets, database imports, and code editors. Trimming removes these spaces while preserving the actual content and internal spacing.
Developers often use line trimming to clean up indented code or remove trailing whitespace that causes Git conflicts. Data analysts use it to prepare CSV files for import, ensuring that extra spaces don't create empty columns or misaligned data. The tool also removes tab characters, making it versatile for various cleanup tasks.

How Line Trimming Works
Our trim tool processes your text line by line, removing whitespace characters (spaces, tabs, and other invisible characters) from the specified positions. Unlike basic text editors that only trim entire documents, this tool preserves line structure while cleaning each line individually.
The Trim Both mode (default) removes spaces from both the start and end of each line, which is ideal for most cleanup tasks. Trim Start only removes leading spaces, useful when you want to preserve trailing alignment. Trim End removes only trailing spaces, perfect for cleaning up code files where leading indentation must be preserved.
All processing happens instantly in your browser using JavaScript - no server upload required. This makes it safe for sensitive data like financial records, personal information, or proprietary code. The tool can handle large files (up to 5MB) and processes thousands of lines in milliseconds.
Tips for Best Results
- 1.For data with both leading and trailing spaces, use Trim Both mode. This is the most common scenario when copying from PDFs or web pages.
- 2.When cleaning code files, use Trim End to remove trailing whitespace while preserving indentation. Combine with Remove Empty Lines for cleaner code.
- 3.For CSV or Excel imports, trim first, then use CSV Safe to escape special characters. This prevents import errors caused by hidden spaces.
- 4.After trimming, use Text Statistics to verify your character count reduction and ensure all unwanted whitespace was removed.
